In the exploitatation and utilization of Bromus stamineus, we must take the different sowing methods and plant densities into account. They have heavy influences on the forage especially in terms of the forage growth. The salt, temperature and water are important factors that affect the seeds germination,which deciding the germination time and germination place.we designed four temperature (15℃,20℃,25℃,30℃) and NaCl density(0.3%,0.6%,0.9%,1.2%) and PEG density(0.126g/gwater,0.186 g/gwater,0.232 g/gwater,0.270 g/gwater).

Every treatment combination has 4 replications.(1)The germination indexes of the former are higher than that of the latter; the germination of the former is stimulated by NaCl density of 0.3 %, while that of the later is restrained by all kinds of NaCl density.(2)With increasing of temperature and PEG indesity,the order of germination rate and vigor of Bromus stamineus and Bromus inermis is decreaced.(3)Under treatment of broadcast sowing and plant density of 549kermels·m~(-2), Bromus stamineus has the highest bud rate, fresh weight, seed yield, while treated with 25cm row spacing and 412kermels·m~(-2) plant densities, tillers, plant height, growth rate increased to the top;(4) Under treatment of broadcast sowing and plant density of 549kermels·m~(-2), its growth rate is took second place, while treated with 15cm row spacing and 824kermels·m~(-2) plant densities, it has the highest seed yield
3撒播时,引进种在播种密度为549粒·m~(-2)处理下单位面积出苗率最高,分蘖数最多,鲜重最大,单株最高,种子产量最大;生长速度在播种密度为412粒·m~(-2)处理下生长最快,密度为549粒·m~(-2)处理下稍次之,结合方差分析可以初步确定它在撒播时的播种密度为549粒·m~(-2);(4)条播时,在行距为25cm、播种密度为412粒·m~(-2)处理下单位面积分蘖数最多,鲜重最大,单株最高,生长速度最快;种子产量在行距为15cm、播种密度为824粒·m~(-2)处理下最大,在行距为25cm、密度412粒·m~(-2)处理下次之;结合方差分析,就3种规格的行距来说,引进美国无芒雀麦条播时的行距为25cm,播种密度为412粒·m~(-2);就这两种播种方式来说,应该选择撒播。
